UMBRE LLA -NOTCH;

SPECIFICATION forming part of Letters Patent No. 768,805, dated. August 30, 1904.

Application filed December 14,1903. Serial No. 185,081. (No model.)

- matching flange, so that when the two tubes are assembled the flanges form a groove for the reception of the wire used to bind together the ribs and notch. In order to stand the usage, and more particularly the rough usage,

to which umbrellas are subjected, this notch has its flanges stiffened by embossments between the cuts or kerfs for the ribs.

In the accompanying drawings, illustrating the invention, in the several figures of which 5 like parts are similarly designated, Figure l is a side elevation. Fig. 2 is a top plan view of the inner tube. Fig. 3 is a cross-section of the inner tube, taken on line A B, Fig. 2.

Fig. 4 is a top plan view of the outer tube.

3 Fig. 5 is a cross-section of the outer tube,

taken on line C D, Fig. 42. Fig. 6 is a crosssection of the two tubes assembled, representing a finished notch.

One member, Figs. 2, 3, and 6, has a tube 1, the upper end of which is provided with a substantially horizontal flange 2, terminating in an upwardly-flared rim This flange is provided with as many radial cuts or kerfs 4 as there are ribs in the umbrella, and these 4 cuts or kerfs extend inwardlysubstantially to the tube. Between these cuts or kerfs the flange is provided with upwardly-eXtending embossments 5, which serve to stifien and reinforce the flange, so as to enable it to withstand the shocks of impact or bangingto which the umbrella is subjected in use, and thus aid in preventing the deformation of the notch and consequent displacement or derangement or the ribs and their retaining-wire. The other member of the notch, Figs. 4, 5, and 6, 5 has a tube 6 of sufficiently larger internal diameter than the external diameter of the tube 1 to permit the two tubes to be crowded together. The tube 6 has a substantially horizontal flange 7, terminating in a down- \vardly-flared rim 8, and cuts or kerfs 9, similar to the cuts or kerfs 4, are made in the flange, and embossments 10 are made in this flange between its cuts or kerfs in a direction the reverse of that of the embossments 5 and for a like purpose. When the two members of the notch are assembled, as in Figs. 1 and 6, their flanges flare away from each other, and thus form a circumferential groove in which is laid the wire used to bind the ribs to the 5 notch, the horizontal portions of the flanges forming the base of the groove in alinement with the eyes in the ribs and the cuts orkerfs extending beyond such base so as to receive the ribs and permit of their pivotal move- 7 ments.

Thelower end of the inner tube may be spun or flanged outwardly or the tubes may be otherwise intimately united so as to provide against longitudinal and lateral displacement of one tube upon the other.

The members of the notch may be drawn, stamped, or otherwise conveniently and economically produced from sheet metal, such as brass, and readily assembled, and the notch finished in any desired manner.

The invention is applicable as well to the stretcher-notcli as to the rib-notch.
